Napa Syn 5W-30 5k 1996 Volvo 850 GLT

This was going to be an initial baseline UOA for this vehicle but near the end of the interval I changed out the fuel injectors and one of them was stuck open so it dumped fuel into the engine. I started the engine and then realised something was wrong and discovered the faulty injector and changed it out. Ever since then the engine has had a ticking noise until it warms up. The oil was run for about another 400 miles after this happened.

I really like there report format. Where did you get the kit and what was the cost?

Looks fine going up to a 40 grade on a quarter century old engine is a good choice.

The kit is from merchant automotive and the analysis is done by Apex Oil Lab, it's $25. I got it because it seems they use to also include TAN as well as 40C viscosity and VI. I guess they have removed those components from the standard test, but still it includes TBN.

Phosphorus and Zinc both look higher than typical for an SN/GF5 oil, did you happen to use a ZDDP additive?

 

[logscool]

Definitely no ZDDP add on the last fill. I doubt there was any before that either, it was previously getting standard shop oil changes.

TBN warning limits Special for BlackStone which use 1.0 from Moon

Moly is a wear metal, not an additive?

Is that place US based? I'd like to do my Odyssey with supertech hm

Personally I like to see the universal averages for the same engine as presented by Blackstone. Although not exactly the same engine, my 2001 V70XC with the 2.4 liter 5-cylinder light pressure turbo has the following universal averages:

Al: 3
Fe: 11
Cu: 4
Pb: 2

Your numbers, particularly Iron and Lead, are quite a bit higher. Lead comes from bearings; I'd be worried if that number increases over time.
